HMD2M32M4E/4EG
8Mbyte(2Mx32) EDO Mode, 1K Refresh 72Pin SIMM, 5V Design
Part No. HMD2M32M4E, HMD2M32M4EG
GENERAL DESCRIPTION
The HMD2M32M4E is a 2M x 32bit dynamic RAM high-density memory module. The module consists of four CMOS 1M
x 16bit DRAMs in 42-pin SOJ packages mounted on a 72 -pin, double-sided, FR-4-printed circuit board.
A 0.1 or 0.22uF
decoupling capacitor is mounted on the printed circuit board for each DRAM components. The module is a single In -line
Memory Module with edge connections and is intended for mounting in to 72 -pin edge connector sockets. All module
components may be powered from a single 5V DC power supply and all inputs and outputs are TTL -compatible.

NOTES
1.An initial pause of 200ms is required after power-up followed by any 8 /RAS-only or /CAS-before-/RAS refresh cycles
before proper device operation is achieved.
2.VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Transition times are measured between
VIH(min) and VIL(max) and are assumed to be 5ns for all inputs.
3.Measured with a load equivalent to 2TTL loads and 100pF
4.Operation within the t RCD(max) limit insures that t RAC(max) can be met. t RCD(max) is specified as a reference point only. If t RCD
is greater than the specified t RCD(max) limit, then access time is controlled exclusively by t CAC.
5.Assumes that t RCD ³ tRCD(max)
6. tAR, tWCR, tDHR are referenced to tRAD(max)
7.This parameter defines the time at which the output achieves the open circuit condition and is not referenced to V OH
or VOL.
8. tWCS, tRWD, tCWD and tAWD are non restrictive operating parameter.
They are included in the data sheet as e lectrical characteristic only. If t WCS ³ tWCS(min) the cycle is an early write
cycle and the data out pin will remain high impedance for the duration of the cycle.
9. Either tRCH or tRRH must be satisfied for a read cycle.
10. These parameters are referenced to the /CAS leading edge in early write cycles and to the /W leading edge in read write cycles.
11. Operation within the t RAD(max) limit insures that t RAC(max) can be met. t RAD(max) is specified as a reference
point only. If t RAD is greater than the specified t RAD(max) limit. then access time is controlled by t AA.
